Looking at getting a water blaster to clean exterior of my house (amongst other things), at highest point its probably between 6-7m high although I can use a small ladder to get some of the way up.
Anyone have any recommendations? Cladding is corrugated steel so if anybody has any recommendations for a particular cleaning concentrate suitable that would be great, otherwise I'm sure I can find something.
Alternatively if somebody has any other suggestions of ways I could clean exterior I'm keen to hear. Should note house is coastal.
